dcf047c4 - add api_base to _client_params (community version of #14393) (#14644)

add api_base to _client_params (community version of #14393) (#14644) - **Description:** This PR adds `api_base` to `_client_params` in the `chat_model` of LiteLLM to ensure it's included in API calls. Previously, `api_base` was set on the client but was not included in the parameters passed to the completion function. This change ensures that `api_base` is correctly passed to all API calls. - **Issue:** #14338 - **Tag maintainer:** @hwchase17 @agola11 - **Twitter handle:** @LMS_David_RS
